Before actually beginning the grinding work, test the grinder by first clearing the area
of all other personnel. Make sure the wheel guard is in place and that you are wearing
eye protection. Turn the grinder “on”, and make sure the grinder runs smoothly and
shows no abnormalities.
Duration of the trial run is as follows:
When depressed center wheel is replaced .................. 3 minutes or more
When starting daily work .............................................. 1 minute or more
9. Use only properly rated depressed center wheels

Using a depressed center wheel rated less can lead to wheel disintegration during
operation and cause serious bodily injury.
10. Check the push button
Make sure that the push button is disengaged by pushing push button two or three
times before turning on the grinder. (Fig. 5)
